A packet-scheduling strategy for heterogeneous traffic of Internet of Things

In this paper, we give classification for various traffics in Internet of Things according to such features as packet length and importance, and propose priority-based scheduling strategy for efficient packet transmission. Detailed theoretical analysis based on one-server queuing theory is provided to show the superiority of short-packet-first non-preemptive strategy over other strategies. And by simulation experiments in NS2, we verify the effectiveness of our method in term of such performance metrics as end-to-end delay, packet delivery ratio and processing overhead.
